Description:
|
In the wild, Crocea Clams are generally found in large colonies. They secrete a substance from their byssal muscles in order to bore into rock or coral. Many Crocea Clams may be found deeply rooted in limestone. Once a Crocea Clam has burrowed into a location, it does not move. It is in fact damaging to yank at a Crocea Clam, as tissue associated with the byssal gland may become seriously damaged. In a home aquarium, you should place your Crocea Clam in a shallow area with intense light, and plan not to move it again. A hardy species, Crocea Clams seem better able to tolerate fluctuations in environmental conditions, and brisk water movement, than many other giant clam species. Of course, in a well-maintained system, variances in water condition should be kept to a minimum. In a home aquarium, Crocea Clams should be placed in shallow areas of the tank with plenty of light. Insufficient light will cause dull brown or bleached coloration. Also, these clams prefer a live rock substrate to a sandy substrate. The smallest of the Giant Clams, a mature Tridacna crocea measures between 4 and 9 inches (12 to 23 centimeters). The mantle shows a variety of colors and patterns including blue, purple, yellow, green, gold, orange, and brown. Lines, spots, or blotches of yellow, blue, and green may also be present. Crocea Clams, for the most part, lack deep vertical folds on their shells. The smooth shell is symmetrical and covered in scutes placed close together. While captive raised Crocea Clams have scutes on both their upper and lower shells, wild caught specimens will have scutes only on their upper shells, due to burrowing activity wearing off the scutes of the lower shell against the rock. Small tentacles cover the inhalant siphon. The byssal opening is generally wide and long on this clam.
